That would be interesting to know more about. What's the point of paying the speed hit of spectre (and meltdown?) mitigations if they are ineffective?
It's not worth it on older CPUs. I turned them off.
I understand browsers already have some protection against them now. I don't see the point in slowing down the entire system, either I trust the apps I have or I don't.
I don't believe a magic packet containing a melted down spectre is going to smash through my router and everything else and turn into skynet on my humble PC.
Because the current mitigations were believed to attack the known affected code paths.

This may refer to the whole thing working, or just the KASLR bypass part.
